Patent number: 8855986Abstract: A method, system and computer program product is disclosed for utilizing proxy models to evaluate a subterranean reservoir. The method includes constructing a proxy model from a set of sampling points to approximate simulation outputs of a reservoir model. The set of sampling points is updated by adding at least one new sampling point that is selected from a location associated with surface non-linearities such as gradients, curvature, and bending energy. Response surface values at new sampling points and distances to existing sampling points can also be used to evaluate new sampling points. Proxy models are refined with the updated set of sampling points until the proxy model satisfies a predetermined stopping criterion, such as when a predetermined number of iterations are reached or when changes to the response surface are below a predetermined threshold.Type: GrantFiled: September 1, 2011Date of Patent: October 7, 2014Assignee: Chevron U.S.A.

Patent number: 8849639Abstract: An example system includes interconnected modeling modules that share knowledge to create a unified earth model dynamically representing a subsurface site. The system models and may simulate subsurface operations associated with, for example: hydrocarbon production and stimulation, natural gas storage, carbon capture and storage, aquifer maintenance, geothermal energy production, and in-situ leachable ore processing. The system integrates a reporting module, and also an economic module to evaluate cost versus benefit of each subsurface operation. A related example method for performing subsurface engineering includes generating a model of a subsurface site including a geological horizon, obtaining an offset relative to the geological horizon, and locating an operation based on the offset. When field data update the model in real time, positions of 3D objects and 3D surfaces are dynamically updated in the model, including the positions of the modeled operations.Type: GrantFiled: September 17, 2010Date of Patent: September 30, 2014Assignee: Schlumberger Technology CorporationInventors: Alan Lee Brown, Simon David Bulman, Martin Crick, Gilles Mathieu, Russ Sagert, Peter Wardell-Yerburgh

Patent number: 8694297Abstract: A porous medium exploitation method having application to petroleum exploitation is disclosed using coupling between a reservoir model and a near-wellbore model for modelling fluid flows. Fluid flows within the medium are simulated using a reservoir simulator and a near-wellbore simulator.

Patent number: 8682620Abstract: A method of designing a die cavity that may include performing a flow analysis using characteristics of a predetermined die cavity, density and rheological properties of a material, and a flow rate of the material to calculate the pressure distribution exerted on the die cavity and cross-sectional flow profile. The method further includes a structural analysis using the calculated pressure distribution and structural characteristics of the die cavity to calculate a deformed die cavity. The flow analysis is repeated using the characteristics of the deformed die cavity to calculate a pressure distribution exerted on the die cavity and cross-sectional flow profile. The outcome is compared to determine if the pressure distributions and/or cross-sectional flow profiles converge. These steps are iteratively repeated until convergence of the pressure and/or cross-sectional flow profile is observed. The variation of the cross-sectional flow profile is analyzed to determine if it is below a predetermined tolerance.Type: GrantFiled: November 19, 2010Date of Patent: March 25, 2014Assignee: The Procter and Gamble CompanyInventors: Jianjun Feng, Eric Paul Granberg, Maxwell Joseph Wingert

Patent number: 8676560Abstract: In a normal operation, a physical unit simulator is allowed to speculatively perform high-speed continuous execution. Only when an actual input comes in, a speculative input and the actual input are compared with each other. Thereafter, in response to inconsistency between the inputs, the physical unit simulator is returned to a point closest to the point of the actual input and is allowed to execute a variable step module to reach the point of the actual input. Upon arrival at the point of the actual input, the simulator is shifted back to the high-speed continuous execution from there. Thus, a processing speed of the simulator can be significantly improved.Type: GrantFiled: June 9, 2009Date of Patent: March 18, 2014Assignee: International Business Machines CorporationInventors: Koichi Kajitani, Hideaki Komatsu, Shuichi Shimizu
